A82-1

Overview

The A82-1 is a general-purpose RF amplifier from MACOM Technology Solutions, designed for operation within the 10 MHz to 300 MHz frequency range. It features a gain of 19 dB and a noise figure of 2.8 dB. The device operates at 15 V with a current draw of 50 mA. Key performance metrics include a P1dB compression point of 15 dBm and an OIP3 of 26 dBm. It utilizes a TO-8-4 through-hole package and functions reliably between -40°C and +125°C.

Feature Summary

• Discrete hybrid design utilizing thin film manufacturing processes for accurate performance and high reliability
• Cascadable architecture suitable for multi-stage signal amplification applications
• General-purpose RF amplification optimized for broad bandwidth coverage

Applications

• GPS signal processing systems
• RF front-end modules requiring low noise amplification
• Test and measurement equipment instrumentation

Procurement Notes

Verify the specific datasheet version corresponding to the A82-1 part number, as documentation may vary between 20-250 MHz and 10-300 MHz specifications. Confirm that the TO-8-4 package matches your PCB footprint requirements. Ensure operating conditions remain within the stated voltage and temperature limits to maintain specified gain and noise performance.

Selection Notes

Select this component when a cascadable, general-purpose amplifier is required for frequencies up to 300 MHz. The TO-8-4 through-hole package dictates mechanical integration constraints. Consider the 15 dBm P1dB limit for linearity requirements and the 2.8 dB noise figure for sensitivity-critical paths. Verify power supply stability at 15 V to ensure consistent operation across the industrial temperature range.

Part Context

The A82-1 belongs to MACOM's discrete hybrid RF amplifier family, distinguished by its use of thin film technology for precision. Unlike monolithic ICs, this hybrid design offers robustness and cascadability. It serves as a foundational building block for analog RF chains where reliable gain and noise performance are prioritized over miniaturization.
